OIL-CAN.

SPECIFICATION forming part of Letters Patent 1-\To. 721,134, datedFebruary 24, 1903. Application tiled October 25, 1902. Serial No.128,797. (No model.)

To .o1/ZZ .wh/0m, it may concern,.-

Beit known that I, THEoPHILUs W. ALEX- ANDER, a citizen of the UnitedStates, residing at Burlington, in the county of Des Moines and State ofIowa, have invented certain new and useful Improvements ,in Oil-Cans;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it lappertains to make and use the same.

opposite end.

It further consists in detachably combining said tube with an oil can ortank and in providing said tube at its lower end with a sleeve orstopper, preferably of tapering form, adapted to t within a thimble ofcorresponding form or construction secured in the top of said can.

In the accompanying drawings, illustrating the preferred embodiment ofmyinvention, and in which like reference characters designate similarand corresponding parts, Figure 1 is an elevation of my improved oil canor tank. Fig. 2 is a longitudinal section. Fig. 3 is a detached view ofthe blowpipe, and Fig. 4 is a longitudinal section through saidblowpipe.

Referring to the drawings, 1 is a tank having a top provided with theusual opening forv filling the can. Said top is provided with an opening4, having secured around the edges thereof a depending (preferablytapering) thimble 5, adapted to receive a correspondingly-formed stopperor sleeve 7, secured upon the lower end of a blow-tube 8. Also seycuredtothe lower end of said tube is a valve 8a, which is preferably oftubular form, havingone or more ports 8b opening just below the end ofthe blowpipe. 4 The sum of the areas of said ports, if `there be morethan one, or the area of a single port, however, should preferably notbe as great as the area of the opening in the base of the valve. Withinthe valve-cage is a ball 9, formed of any suitable metal, adapted toseat above said'lateral ports, and thereby close the valve, but normallyadapted to rest in the lower portion of said valve below said ports.

tain said ball within the valve-cage when it descends below said ports.This can or tank Y is also provided with a Vdischarge-tube 10,

which preferably has its upper end goosenecked and its lower endarranged near the bottom of the can. Another opening 11 is arrangedwithin the top of said can and provided with a stopper 12, the purpose.of which will hereinafter appear.

In using my device the air is forced through -the blowpipe into the canproper to create a pressure upon the upper surface of the oil orcontents of the can, said air being forced through the lateral ports 81into the can, the

Said Valve is y preferably crimped at the lower end to revalve 9 restingupon the crimped lower end of the tube 8. The pressure thus introducedinto said can will of course be exerted to effect the lifting or forcingof the oil up through the discharge-tube l0 into a receptacle or vesselfor its reception. The operator having secured the. desired air-pressurewithin the can may cease to force more air into the can,

whereupon the airpressure will force the ball-valve up and seat itabovethe lateral ports 8b, thereby preventing escape of air through theblowpipe. As the delivery of the oil or contents continues theair-pressure will gradually decrease and finally allow the valve to dropbelow the ports 8b and lodge in the lower end of the blowpipe. If,however, the receptacle in the operation ofk being lled becomes fullbefore all the compressed air is expanded, this superiuence of airA maybe liberated by withdrawing the cork or stopper 12, thereby stopping theHow of the oil from the discharge-tube 10.

My invention provides a device of simple construction which will beefficient in use and which may be operated with ease. The blowpipehaving the valve at the lower end IOO thereof may be readily detachedfrom the can for the purpose of cleaning the valve should it becomeinoperative in consequence of some obstruction in the valve or othercause.

I am aware that changes may be made in the details of construction andarrangement of parts herein shown and described, and I therefore reservethe right to make such modifications as fairly fall within the scope ofmy invention.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a device of` the character described, the combination, with areceptacle or can, of a blowpipe having lateral ports above its lowerend anda valve-.seat located interiorly of said blowpipe above saidports, said blowpipe having inward projections at its extreme lower end,and a ball-valve arranged in its lower end and adapted to rest upon saidprojections when pressure is delivered through said pipe, the airpassing through said ports into the receptacle, and after the blowingoperation, said valve being again adapted to rest below said ports.

2. In a device of the character described, the combination, with areceptacle or can having a thimble arranged around an opening in the topthereof, of a blowpipe having a sleeve arranged upon its lower end anditting into said thimble, said sleeve having inward projections at itsextreme lower end and lateral ports above said lower end, said sleevealso having a valve-seat above said ports,l and a ball-valve adapted torest upon said inward projections when the air-pressure is beingdelivered through said ports into said can, and,upon the removal of theblowing pressure, again adapted to rest upon said lower inwardprojections.

In testimony whereof I ax my signature in presence of two witnesses.

THEOPHILUS W. ALEXANDER.
